Tongri/ factory price/ Small friction/ Cylindrical roller bearing
Product details
cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single and double row full complement bearings (without a cage) and split bearings.
Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. Cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with a cage.
About us
Hebei zengshan Intelligent Science and Technology Co., Ltd. is a professional manufacturer of CNC machine tools, paper tube equipment, paper making machine, corrugated box equipment, and coating machine. In 1990, we jointly produced textile bobbins and spiral bobbins with Taiwan Haoli company. In 1992, we developed and launched a complete set of semi-automatic cone tube and spiral tube equipment. With advanced processing technology, processing means and excellent product quality and perfect service, our products are sold to all parts of the country.
In 2006, on the basis of absorbing foreign advanced technologies such as Germany and South Korea, qzd-68 full-automatic cone paper tube production line was developed and developed. The machine adopts the new technology and new technology of Mechatronics to realize the production of low labor, low energy consumption, high efficiency and high quality cone paper tube.
In 2012, through communication and discussion with many customers at home and in combination with international advanced experience, the original equipment was improved and promoted, and a new full-automatic cone paper tube production line zsz-2012 was launched, further improving the utilization rate of raw materials, which was unanimously recognized by customers.
